Deep-sea study reveals cause of 2011 tsunami
The devastating tsunami that struck Japan's Tohoku region in March 2011 was touched off by a submarine earthquake far more massive than anything geologists had expected in that zone. Now, an international scientific team has published a set of studies in the journal Science that shed light on what caused the dramatic displacement of the seafloor off Japan's coast. The findings also suggest that other zones may be at risk of similar huge earthquakes.

An ecosystem-based approach to protect the deep sea from mining
A new paper describes the expert-driven systematic conservation planning process applied to inform science-based recommendations to the International Seabed Authority for a system of deep-sea marine protected areas to safeguard biodiversity and ecosystem function in an abyssal Pacific region targeted for nodule mining (e.g. the Clarion–Clipperton fracture zone, CCZ).

University of Tennessee study finds crocodiles are cleverer than previously thought
Vladimir Dinets, a research assistant professor at UT, is the first to observe two crocodilian species -- muggers and American alligators -- using twigs and sticks to lure birds, particularly during nest-building time.

Rising ocean acidification leads to anxiety in fish
A new research study combining marine physiology, neuroscience, pharmacology, and behavioral psychology has revealed a surprising outcome from increases of carbon dioxide uptake in the oceans: anxious fish. Scientists at Scripps Institution of Oceanography at UC San Diego and MacEwan University in Edmonton, Canada, have shown for the first time that rising acidity levels increase anxiety in juvenile rockfish, an important commercial species in California.

Sea-level rise to drive coastal flooding, regardless of changes in hurricane activity
Clamor about whether climate change will cause increasingly destructive tropical storms may be overshadowing a more unrelenting threat to coastal property -- sea-level rise -- according to a team of researchers writing in the journal Nature this week.

Coastal sea change
Carbon dioxide pumped into the air since the Industrial Revolution appears to have changed the way the coastal ocean functions, according to a new analysis published this week in Nature. A comprehensive review of research on carbon cycling in rivers, estuaries and continental shelves suggests that collectively this coastal zone now takes in more carbon dioxide than it releases. The shift could impact global models of carbon's flow through the environment and future predictions related to climate change.

The big unknown: Factoring marine sediments into climate calculations
A new EU-funded project called "OCEAN-CERTAIN" has been created to improve our understanding of a basic marine biology mechanism, so that its significance in shaping future climate change is clearer. The project will be led by researchers from the Norwegian University of Science and Technology in Trondheim, and will examine and compare the situations in different ocean areas on the planet.

Humans threaten wetlands' ability to keep pace with sea-level rise
Left to themselves, coastal wetlands can withstand rapid levels of sea-level rise. But humans could be sabotaging some of their best defenses, according to a Nature review paper published Thursday from the Virginia Institute of Marine Science and the Smithsonian Environmental Research Center.

New study identifies 5 distinct humpback whale populations in North Pacific
The first comprehensive genetic study of humpback whale populations in the North Pacific Ocean has identified five distinct populations -- at the same time a proposal to designate North Pacific humpbacks as a single "distinct population segment" is being considered under the Endangered Species Act.

Scripps leads first global snapshot of key coral reef fishes
In the first global assessment of its kind, researchers at Scripps Institution of Oceanography at UC San Diego have produced a landmark report on the impact of fishing on a group of fish known to protect the health of coral reefs. The report, published in the journal Proceedings of the Royal Society B (Biological Sciences), offers key data for setting management and conservation targets to protect and preserve fragile coral reefs.

Expedition yields unexpected clues to ocean mysteries
A University of Houston geoscientist and his colleagues reveal new discoveries about Earth's development, following a major international expedition that recovered the first-ever drill core from the lower crust of the Pacific Ocean. Jonathan Snow and Kathryn Gillis led a team of 30 researchers from around the world on the expedition, finding a few surprises upon penetrating the lower crust of the Pacific. Their findings are described in the Dec. 1 issue of Nature.

Model: Ocean currents shape Europa's icy shell in ways critical for potential habitats
In a finding of relevance to the search for life in our solar system, researchers have shown the subsurface ocean on Jupiter's moon Europa may have deep currents and circulation patterns with heat and energy transfers capable of sustaining biological life. The findings, summarized in this week's online edition of Nature Geosciences, are based on numerical models accounting for the formation of the chaos terrains, one of Europa's most prominent surface features.

Antarctic fjords are climate-sensitive hotspots of diversity in a rapidly warming region
In the first significant study of seafloor communities in the glacier-dominated fjords along the west Antarctic Peninsula, scientists expected to find an impoverished seafloor highly disturbed by glacial sedimentation, similar to what has been documented in well-studied Arctic regions. Instead, they found high levels of diversity and abundance in megafauna. The difference can be explained by the fact that the subpolar Antarctic is in an earlier stage of climate warming than the Arctic.

Silent stalkers of dark ocean waters
The mating roar of a male harbor seal is supposed to attract a partner, not a predator. Unfortunately for the seals, scientists have found evidence that marine-mammal-eating killer whales eavesdrop on their prey. Previous research had shown mammal-eating killer whales are nearly silent before making a kill, neither vocalizing nor using their echolocation. The likely reason, researchers say, is the excellent hearing of the seals, porpoises, and other animals the whales stalk.

SU biologist develops method for monitoring shipping noise in dolphin habitat
A biologist in Syracuse University's College of Arts and Sciences has developed a system of techniques for tracking ships and monitoring underwater noise levels in a protected marine mammal habitat. The techniques are the subject of a groundbreaking article in Marine Pollution Bulletin, focusing on the bottlenose dolphin population in Scotland's Moray Firth.

UCSB researcher shows microplastic transfers chemicals, impacting health
With global production of plastic exceeding 280 metric tons every year, a fair amount of it makes its way to the natural environment. However, until now researchers haven't known whether ingested plastic transfers chemical additives or pollutants to wildlife. A study conducted by UCSB's National Center for Ecological Analysis and Synthesis shows toxic concentrations of pollutants and additives enter the tissue of animals that have eaten microplastic. The findings are published in Current Biology.

Arctic study shows key marine food web species at risk from increasing CO2
A research expedition to the Arctic, as part of the Catlin Arctic Survey, has revealed that tiny crustaceans, known as copepods, that live just beneath the ocean surface are likely to battle for survival if ocean acidity continues to rise. The study found that copepods that move large distances, migrating vertically across a wide range of pH conditions, have a better chance of surviving.
